Beginner Crypto Toolkit
When it comes to CTF challenges and cybersecurity, having a proper toolkit becomes an essential part; enabling one to use the underlying knowledge with ease. Personally I rather centralize my practice of cryptography in Python.

Narnia0
In this post I’m going to share my write-up for the first level of Narnia series of challenges from OvertheWire. This post is not just a CTF write-up, but an excuse to learn about computers and security. A base knowledge of Linux operating system, programming (Especially in C) and Assembly Language is needed. Enjoy! :)

Minimal Assembly Reference
Assembly language is without doubt one of the most important topics in binary reverse engineering and exploitation.
Of course Assembly is huge and there are lots of great resources to learn from. This post however represents an abstract of what I’ve learned during an assembly course. You can find it here or here. It’s more appropriate in case you want to look up instructions and read binary.
Hope it comes useful :) -
Forensics Lessons
Recently I’ve been engaging with some forensics challenges. Honestly this was my first encounter with this category in CTF.
I’ve discovered a lot during the progress of solving and learned a lesson or two.
So I hope sharing them would be useful for you as well. Enjoy :)
